Digital camera w/ water sealing

[ecce38]

I was up until 2am doing my taxes (blah), but the end result was very good. As such I will be taking my "play money" and buying the Pentax K10 digital camera (check dpreview.com for specs/reviews). Since I already have two pentax lenses, I am, as they say in poker, "pot committed" to this brand. Since one of the big selling points is the water sealing technology, I was wondering if anybody here has one and has actually taken it out to the river/lake/pond/puddle and could post a quick comment about it faired in those envirnoments. Otherwise, what are one or two of the big no no's of using digital cameras on fishing trips (short of not dropping it in the dang river!)? Maybe something not obvious but very important.

ecce out....
